         5 . A burner comprising:
 a supply part configured to supply gas;   a distribution part configured to receive gas from the supply part; and   a plurality of parallel combustion parts comprising a plurality of flame holes, which are formed in at least one side in a direction perpendicular to a gas flow direction for receiving gas from the distribution part and allowing combustion of the received gas.   
     
     
         6 . The burner according to  claim 5 , wherein the combustion parts are disposed at an upper part of an oven chamber and elongated in a front-back or right-left direction. 
     
     
         7 . The burner according to  claim 5 , wherein the distribution part is elongated in a right-left direction of an oven chamber, and the combustion parts branch off from the distribution part and extend in a front-back direction of the oven chamber. 
     
     
         8 . The burner according to  claim 7 , further comprising a connection part configured to connect ends of the combustion parts branching off from the distribution part such that some of gas flowing in the combustion parts is transferred to the connecting part. 
     
     
         9 . The burner according to  claim 5 , wherein the supply part extends in a front-back or right-left direction of an oven chamber,
 the distribution part extends in the right-left direction of the oven chamber so as to be connected to an end of the supply part, and   the combustion parts branch off from the distribution part and extends in the front-back direction of the oven chamber.   
     
     
         10 . The burner according to  claim 5 , wherein the supply part, the distribution part, and the combustion parts are formed in one piece. 
     
     
         11 . The burner according to  claim 5 , further comprising a distribution protrusion enabling uniform distribution of gas from the distribution part to the combustion parts. 
     
     
         12 . The burner according to  claim 11 , wherein one of the combustion parts is placed along a line in a direction in which gas is transferred from the supply part to the distribution part, and
 the distribution protrusion is disposed at a position from which the one of the combustion parts branches off from the distribution part.   
     
     
         13 . The burner according to  claim 11 , wherein the distribution protrusion is positioned in a flow passage along which gas is transferred from the supply part to the distribution part. 
     
     
         14 . The burner according to  claim 11 , wherein the distribution protrusion is formed by protruding a portion of at least one of the distribution part and the combustion parts into a gas flow passage. 
     
     
         15 . The burner according to  claim 11 , wherein if gas flows in a direction parallel with a direction in which gas is transferred from the supply part to the distribution part and is then distributed to the combustion part, the distribution protrusion disturbs the flow of the gas. 
     
     
         16 . The burner according to  claim 5 , further comprising a neck part at a position from which one of the combustion parts branches off from the distribution part, the neck part having a cross sectional area smaller than a cross sectional area of the one of the combustion parts. 
     
     
         17 . The burner according to  claim 16 , wherein the cross sectional area of the one of the combustion parts decreases from an upstream side to a downstream side of a gas flow. 
     
     
         18 . The burner according to  claim 16 , wherein the supply part and the distribution part extend in parallel with each other,
 the combustion parts extend in a direction perpendicular to the distribution part, and   the neck part is disposed at a position, from which the most downstream one of the combustion parts in a direction in which gas is transferred from the supply part to the distribution part is branched off from the distribution part.   
     
     
         19 . The burner according to  claim 5 , further comprising a plug assembly configured to ignite gas at the combustion parts. 
     
     
         20 . The burner according to  claim 19 , wherein the combustion parts comprise:
 a first combustion part extending from a center portion of the distribution part in a front-back direction of an oven chamber;   a second combustion part extending from a lateral end portion of the distribution part in the front-back direction of the oven chamber; and   a third combustion part extending from the other lateral end portion of the distribution part in the front-back direction of the oven chamber,   wherein the plug assembly ignites gas to be discharged through the first combustion part to form a flame, and the flame propagates along the distribution part to gas to be discharged through the second combustion part and the third combustion part.   
     
     
         21 . A gas oven comprising:
 an oven chamber in which food is cooked; and   the burner of any one of  claims 1  to  20 , the burner being disposed at a side of the oven chamber for provide heat to the oven chamber for cooking the food.
